You know Jerry, I was on the THX site a few times reviewing their qualifications to be certified. It is no joke. You can make an argument that if all your equipment is THX - certiified, it would probably guarantee some things, make some things easier for yourself and custom installer, and rule some other things out.
I had no idea how extensive they were. Question though, an exclusive and flagship no holds barred product like this, unless I`m missing something here, why are we still talking DVI, and not HDMI here?

DVI is ROCK SOLID in terms of "hand shake" issues and video quality. No sense buying a $100K anything only to be outdone by the ever tricky HDMI. You're going to find a lot of the higher ticket video items still use DVI only. Just ask Jerry about HDMI. His Meridian projector is DVI only.
